jsfetzik,
Are you comparing "Tenergy to Eneloop" or "Tenergy LSD to Eneloop" when you say "last longer on the shelf"? There are newer Tenergy LSD batteries that are same technology as Eneloop. Or were you comparing the older Tenergy that are regular NiMh?
Plain old Tenergy. I have not used the Tenergy LSD.
I believe I have a couple long shelf life batteries of another brand, but I can't remember which off the top of my head.
I have about 20-25 Eneloops in both AA and AAA and have no problems with them in various uses. Although I only just got my first light sabers, so do not have specific experience with them in light sabers.
